Be it known that I, AUeUsr LIivDonEN, of

-Mo line, county of Rock Island, and State of Illinois, have Invented anew and useful Imerence more particularly tothe type of plow in which awheeled frame is equipped with one or more plowing-disks.

The invention consists in various improvements directed to the formandconstruction of the frame to ada t the machine to be convetted into asin erdiskfa double-disk,

or triple-disk p ow; to the mechanism for raising,"lowering, andcontrolling the front furrowwheel; to the mechanism for raising,

In the accompanying drawings, Figure 1 is a top view of my improvedmachine with the members of the frame connected and assemblql for athree-disk plow. Fig. 2 is a similar view showing the frameconvertedinto ,a'two-disk plow. Fig. '3 is a side eleva tioii of the imroved machine as viewed from Fig. 4 is a rearperspective view showingthe normal oplierative position ig. 5 is an end view showing thefurrow-wheel raised for transportation. Fig. 6 is a front elevation ofone of the disk-bearings. cal section through the same on the line a a.Fig. 8 is a horizontal longitudinal section on Fig. 9 is a transversevertical viewed in the direction of the arrows on said line, showing howthe latch for the rear casterwheelis held free of the stem of said wheelanddiitof contact with the same.

Referring to the drawings, as shown are ticulafl'y 'n Figs. 1', 2, and3, the frame 0 the machine comprises a plurality of complementarydetachable frame members or sections in the present-instance three innumber,afor- Fig. 7 is a vertiward one,A,a rear one, B and anintermediate one, C-thesaid sections being of such form that .they areadapted to be detachabl .coiineoted together in,the ,order shown t atis,

. egmith, the...intermediate'sectionconnected dis in frontof this armthe ton e has connected with it a horizontal later-nil named from theframeniembr rectly to the front section and the rearsection connecteddirectly with the intermediate section, or the intermediate section mabe omitted and the rear section connecte directly with the frontsection. The several frame-sections are adapted also to carry each aplowin -disk, a disk a for the front section, a disk I; or the rearsection anda disk 0 for the intermediate section. In order to adapt theseveral sections to be thus assembled and to carry its plowing-disk,each section embodies a draft portion and a disk-carrying arm, thelatter being arranged at an an is with reference to the draft ortion. Te draft ortion of the member A is indicated at a an the disk-carryingarm at a, the draft 7o arms of the several members extending arallel toeach other laterally. rearward, an the disks carried by them thusoverlap ing in the usual manner and each turnin a fi iirro'w furrowwardof the next disk in a van'ce.

In the arrangement of the parts as indicated in Fig. 1, with theframemembers connected to carry three disks, the front and rear disksare respect-ively on oppqsite sides of. the line of draft throu "h'tlietongue D, so that the strain on the ame dueto the resistance offered thepassage of the disks through the ground is evenly distributed on oposlte sides of the frame as a whole which w' I tend to avoid thecrowding of the machine laterally. Q l

I prefer to form the several frame-sections of a length of metal bar of.substantially I form in cross section bentfto'the de'slred fem. 5 m

The front frame-sectional is provided at its forwardextremity with alaterallyfeiilrtelnding e me o arma, dis osed at right angles to tdraft, to w -ch the tongue D is attached, and

I bar 'agonal, brace e, connected withlthediaft 50s by a'diis effectedby setting in between the inner face tion of said member and with thebar E, near its outer end, which latter is upturned, as at a, and givessupport to the front furrowwheel F, as will be more fully describedhereinafter.

The intermediate frame-section C has the forward end of its draftportion placed flatly against and is detachably connected with the rearend of the section A by means of fastening-bolts 1, passed through saidparts from the inside, which'bolts have fastening-nuts ap lied to theirends. 1

he rear frame-section B has the forward end of its draft portion placedflatly against the rear end of the section in advance, to which it isconnected by means of fasteningbolts 2, passed through said parts andprovided with suitable fastening-nuts.

Between the draft portion of the section 0 and the disk-carrying arm bsaid section extends lon itudinally in the direction of the line of drat, as at c, and to this longitudinally extending portion of the frame isattached an upwardly-extending bracket G, provided with a lateralbearing g, in which is mounted the inner end of a crank-axle having onits outer end a land-wheel H, the axle havin fixed to it anadjustinglever it, provided with a locking-dog engaging a toothedsegment h, fixed to the bearing. Extendin laterally furrowward from theend of the dis -carrying arm I) is a horizontal arm I, to which isfirmly attached a block or casting J, in which is mounted the rearfurrow-wheel K, as will be more fully described hereinafter.

The bearings for the several disks are indicated, respectively, by thenumerals 3, 4, and 5, and each comprises a vertical bracketplate 6,Figs. 6 and 7, adapted to be secured to the front of the disk-carryingarm, and an upwardly-inclined cylindrical bearing roper, 7, to receivethe hub of the disk, whic bearing is fixed to the lower end of thebracketplate, with its axis below the carryingerm and extendingobliquely upward and laterally at an angle with respect to the line ofdraft.

The bracket-plates are secured to the car rying-arms of the severalsections in such manner that they may be adjusted laterally along thearms and may also be tipped to vary the di or inclination of the disks.

The latera adjustment of the bearing iseffected by roviding the carryin-arms with a number oi holes arranged side y side to receivefastening-bolts 8 and 9, extending through the bracket-plate and theopenings in the arms and serving to secure the plate firmly butdetachably to the arm, the osition of the plate on the arm bein changedby settin the fastenin -bolts in cfifferent holes.

he tilting of t e bracket-plates in order to change theinclination ordip of the disksis of the bracket-plate and the side of the carrying-armtwo vertical bearing'plates l0 and 11, which rest against the up er andlower projecting edges of the arm an which are ongaged at their upperends by two set-screws 12 and 13, extending loosely through thebracketzplate and having their inner ends threade through nuts 14 and15, held in sockets in the inner face of the bracket-plate, thearrangement bein such that when the set-screws are screw through thenuts by means of heads 15", exposed on the outside of the bracket-plate,their inner ends e aging the bearing-plates will cause the brac at to bethrown outward at its upper end, as shown in Fig. 7, which will tip thecylindrical diskbearing downward an correspondingly adjust the disk. Itwill be necessary in order to effect this adjustment to first loosen thetwo fastening-bolts 8 and 9, which may again be tightened up after thebearing has been adjusted by the screws 12 and 13.

By the lateral adjustment of the disks along their carrying-arms thewidth of the cut made by the disks may be var ed, it being butnecessaryto shift'the front and rear bearings with reference to thecentral one, which atter may be fixed as far as any lateral adjustmentis concerned.

In order that the lateral disk-carr 'ng arms may be firmly braced, so asto hol the disks to their work, I provide a brace-bar 16 for the forwardarm a, and a brace-bar 17 for the arm 0. The brace-bar 1h has its frontend bearing against the rear face of arm a, to which it is secured bythe fastenin bolt 9-, the brace having a number of ho es 16 in its endto receive the fasteningbolt when the latter is chan ed in position onthe arm to adjust the disk latefitlly. The opposite end t e side of tHfdraft portion of the frame member C b means of the bolt .2.' Thebrace-bar l7 as its front end secured in like manner to the rear faceofthe disk-carrying arm 0* and its opposite end firmly bolted to thedraft portion of the frame member B.

The front furrow-wheel F,before alluded to, is mounted on adownwardly-inclined axle extendin vertically in the form of a stem 20and fioosely through a castin or bracket 21, fixed to the upturned end0' the transverse bai- E. The stem has fixed to its upper end the innerforked end of an arm 22, whose o posite end is provided with a swivelinghea 23, connected adjustably by a setscrew 23" with the forward end ofa, rod 24, extendingrearwardly and jointed ,to the side of a verticalhand-lever 25, whiclrhand-lever is within easy reach of the driver, whooccuies a seat 26 on the rear frame member B. he hand-lever is pivotedat its lowerend to the side of a vertical standard 27, risin from thecasting J, to which it is firmly fixe andthe lever is provided withalocking-dog engaging a toothed segment-plate 281011 the upper end of thestandard.- By means of this hand-lover the driver is enabled to turn thefront furrow-wheel in order to control the direction of travel of themachine, as in turning corners. The connection of the front end of therod 24 with the arm 22 is adjustable in order to provide for theoperative connection of the parts when the frame of the machine isshortened or lengthened in assembling the members of'the same forcarryin a greater or less number of disks.

T e furrow-wheel is raised and lowered in order to raise and lower thefront end of the frame by means of a hand-lever 30,- pivoted 'at itslower end to the side of the vertical standard 27 and provided with alocking-dog e agin a toothed segment 31 on the upper err of t e standardand alongside that just described. This lever has swiveled to its side aperforated head 32, through which the rear end of the rod 33 is looselypassed and secured by a set-screw 34, the forward end of said rod beingjointed to one arm 35 of a bell-crank lever 36, pivoted, as at 36', to arearwardly-extending arm 37 on the upper end of the bracket 21. on thebell-crank lever is connected, by means of vertical links 35, with asleeve 37 mounted loo'selzfion the furrow-wheel stem between the for ofthe arm 22, the arrangement bein such that when the hand-lever is pullerearward the forward arm of the bell-crank will be drawn, downward andwill force the stem of the furrow-wheel F downward through thebracketlate, and when the lever is ushcd forwar the stem of thefurrow-whee will be raised-vertically, which actions will respectivelyraise and lower the forward end of the machine. 'A coiled sfirin 38 hasits upper end connected with t e s eeve 37 and its lower end connectedwith the bracket 21 and tends to force thewheel downward and in thismanner assists the operator in raisin the front of the machine when thehandever is unlocked from its segment.

In order to convert the machine from a three-disk plow, as shown in Fi1, to a two-disk plow, as shown in ig. 2, the intermediate .frame memberC is detached from the frame member in advance and from that in the rearby the removal of the fastening-bolts which secure said parts together,the brace-bar 16 being detached from the lateral arm a and the brace-bar17 being detached from lateral arm c. Theframe member C is then removedand the draft portion of the member B is bolted to the draft portion ofthe forward member, the bracear 17 being bolted to the rear face of thedisk-carrying arm a of the forward member. Previous to thedisconnection, of the parts in this manner the set-screws 23 and 34 areloosened,v so as to release the two rods 24 and 33, which connect thetwo handlevers with the front furrow-wheel. and after The other armparts have been connected for a two-disk ow. I V p While I haysillustrated and described the frame of the machine as being made up ofcomplementary members of such a number as to carry three disks, it willbe understood that additional frame members maybe emploied between thefront' and rear members, suc additional members being substantially ofthe form of the intermediate member C.

The rear furrow-wheel K is mounted on a downwardlyinclined axle 40extending laterally from the rear end of a horizontal axlebar 41,,having its opposite end turned upwardly to form a vertical stem'42,extending loosely lghrough' two bearing-1n 43 and 44, project'rearwardly'from the look or caste mg J wit a space between the adjacentendsv ofsaid lugs. The stem 42 is encircled by a collar 45, which issituated between the two bear-in -ln s and rovided with a set-screw 46for olding it y on the stem, the arran ement bein such that the stem iscaab e of a swive g motion in the bearings,

ut is revented from movin up or down when t e set-screw is tightens upand may be adjusted vertically and held in its different adjustments bysliding it through the collar and fastenin the latter in lace thereon.In the norma' o eration of t e machine, as in lowing, this the si e inthe furrow,'its motion furrowward being limited by a locking-latch 50,which permits the wheel to move landward when the machine is turned.This latch 50 is piv-- oted on a horizontal longitudinal axis, as at 51,to the casting J and it is formed at one end with a nose 52, which whenthe low is in action with the wheel traveling in t e furrow enga es thehorizontal axle-bar and holds the whee in the furrow, the latch beinraised from engagement with the axle-bar w 'en-the machine isto beturned to the right.

In transportin from field to fielf it is desirable that'its rear end vberaised much higher than when plowing, and in order to effect this resultthe nose the machine on roads or ow-wheel travels at of the latch 50 isformed with a cam-surface 54, adapted when the opposite end of the latchis raised by means of a handle 55 to enage the upper surface of theaxle-bar and force the vertical stem downward through its bearmgsin thecasting J, and thus elevate the frame of the machine, as shown in Fig.5. It will be necesssary before this elevation of the frame by the latchto loosen the set-screw 46 so as to permit the stem to slidetherethrough, which collar is again tightened on the stem to hold theframe elevated.

In order that the latch. when in the position shown in Fig. 4, with theplow in action, may be maintained in this operative position, ready tocatch the axle-bar as it comes back after the machine has turned to theright, I mount on the latch a movable lockingpin 56, the inner end ofwhich is adapted to engage over a ledge 57 on the casting J and in thismanner revent the latch from tipping downward w en the axle-bar moveslandward from beneath it, the relation of the locking pin, ledge, andlatch being such that normally and while the plow is in action the latchwill be held from resting on the crankaxle and a slight distance aboveit, with the nose of the latch extending downward alongside ofthe axle,so as to prevent the wheel from running out of the furrow, as shown inFig. 9. When the latch is to-be operated, as described, to elevate .theframe of the machine; this locking-pin 1s first withdrawn free of theledge to permit the nose-piece to be turned downwa d. and to engage theaxleoar.
